This Soc has 2 types HS phys. one in combo phy and another stand-alone. please refer the block diagrams in cover-letter. 
	
	1. samsung,exynosautov920-usbdrd-phy => represents hs phy (synopsys phy version-303) and it is same as "samsung,exynos850-usbdrd-phy". used same naming conventions
	2. samsung,exynosautov920-usbdrd-hsphy => represents 'Add-on' HS phy(synopsys phy version-400) with SS phy in combo phy. this is different from "samsung,exynosautov920-usbdrd-phy" (reg offsets and bits are different). 
	samsung,exynosautov920-usb31drd-ssphy =>  represents SS phy in combo phy
